The Problem There are numerous programs under development to revolutionize the current “physical” internet. Most programs attempt to reach their goals by a virtualization of resources or putting in the end users hands access to resource allocation. Some of the leading programs are Planet Lab, Hopi, UCLP and Dragon. Most of these concentrate on subset of issues relating in one way or another with getting dedicated resources on demand or semi-on-demand. All require a preconfigured node or device to allow use of a resource whether physical or logical. But what if we extended this notion to the control plane? What we propose here specifically is a provisional control plane mechanism for total resource creation and control.

Planet Lab • Xen virtual machine • Allow researchers to research protocols etc • Uses real routing information acquired from the commodity internet to present a virtual environment as a “real” simulation • Gives fairly serious resources to researchers e.g. a researchers playground • Overlay network • VINI

Hopi • Hybrid Optical Packet Infrastructure • Leverages network layers to construct a virtual “Light Path” • Deployed but still very conceptual • Working with Dragon on GMPLS etc.

UCLP • User Controlled Light Path • Gives end user access to optical resources • Ethernet in Sonet Framing

Dragon • Uses GMPLS - current sets up VLANs • Allows dynamic lambda switching • Resource Scheduling • Virtual Lambda Switching Router (VLSR) • Network Aware Resource Broker (NARB)

GENI • Based on Planet Lab • Employs notion of virtual router • Highly specialized case; private domain

OARnet/TFN • Uses MPLS for recovery & partitioning • Uses Logical Routers in production • Juniper LR is others VR

Proposal • What if…. • Leverage Planet Lab virtualization and extended overlay notion to… • HOPI like light paths and… • used Dragon as part of the subset for signaling • Finally, what if we could dynamically provision the control plane much like the resources described?

The Problem • The $50,000 question is how is resource discovery, binding and provisioning performed in global and scalable way? • Can we use and slightly alter mechanisms that already exist? • In other words can we use an existing infrastructure as an out-of-band control channel to facilitate creating new infrastructures?

Assumptions • Facilities (POPS) that support new infrastructure deployment generally we be located at facilities that support the current internet • Multicast attributes can be leveraged for resource discovery and bootstrap provisioning • Assuming that both prior assumptions are true we can use the existing internet as an out-band-control channel • The advantage is that it already exists and is ubiquitous in the research and education community

Conclusion • The afore mentioned process does not preclude an iterative and nested process • As such a process could be used widely and global paths • For example, Servers could be allocated as LSR routing engines on link by link basis to construct an LSP if needed. • This might be a way to address the inter-domain resource problem
